Pneumatic Train Pipe Patents (Class 116/55)
  • Patent number: 10745990
    Abstract: The present disclosure relates to a system that includes a shearing ram configured to mount in a blowout preventer. The shearing ram includes a body portion that may move along an axis of movement. The shearing ram also includes a sealing member disposed in a first surface of the body portion. The sealing member is biased away from the first surface in a crosswise direction relative to the axis of movement, such that the sealing member may engage a second surface of a second shearing ram when the first shearing ram and the second shearing ram overlap with one another with respect to the axis of movement.

  • Patent number: 10179580
    Abstract: A brake cylinder maintaining system that combines a brake cylinder maintaining check valve and a quick service limiting valve into a single unit to have lower hysteresis, and thus more precise BCM regulation pressure and a smaller pressure offset. The check valve and quick service valve are coupled to provide a single system having multiple valve seats for selective communication between quick service pressure and brake cylinder pressure on one hand, and between a brake cylinder maintaining pressure and brake cylinder pressure on the other hand.

  • Patent number: 9938794
    Abstract: A ram block assembly enables a very high shearing, breaking, or parting force by utilizing guide rails and passageways within the ram block assembly to accept the rails and gird the rails against deviation from intended trajectory. The ram block rails and cavities enable application of extreme forces, opposing and concentrated within a small area, when actuating the ram block assemblies into the “open” or “close” positions. The ram block assemblies move in opposition, approaching each other and applying opposing forces against any material positioned between the ram block assemblies, and deforming, severing, breaking, shearing, parting, tearing and/or cutting, as the case may be, any said material positioned between the ram block assemblies. The severing of materials in the wellbore is known as “shearing,” and the apparatus performing this shearing operation as shear rams, shear ram blocks, shear blocks or shears.

  • Patent number: 9324228
    Abstract: A pipe system includes a pipe for containing a pipe flow therethrough having a first flow rate, a sampling tube coupled in fluid communication to the pipe for receiving and containing a portion of the pipe flow therethrough, for interacting with the portion of the pipe flow therethrough so as to form a second flow rate of the portion of the pipe flow being an amplification of the first flow rate, and for returning the portion of the pipe flow to the pipe, and a sensor for sensing the second flow rate and for transmitting a signal being a function of the second flow rate.

  • Publication number: 20080276691
    Abstract: A single car test device includes a housing; a source port, on the housing, to be connected to a source of pressurized air; a brake pipe port, on the housing, to be connected to the brake pipe connector; and valves, in the housing, selectively interconnecting the ports to each other and atmosphere to perform tests. A brake cylinder sensor is to be connected to a brake cylinder tap. A sensor module on an interface device, remote from the housing, is to be mounted on the test ports on a control valve for determining pressure at the test ports. A controller is connected to the valves, the sensor module and the brake cylinder sensor and includes a program performing a plurality of component tests which form a single car test. The interface device includes reservoir charging valves controlled by the controller.

  • Patent number: 6282463
    Abstract: A method of selecting pneumatic devices that satisfy specified load, speed and strength conditions to construct a pneumatic system. Data concerning pneumatic actuators, solenoid-controlled selector valves, drive controllers, pipes, pipe joints and exhaust treatment devices is stored in a pneumatic actuator database, a solenoid-controlled selector valve database, a drive controller database, a pipe database, a pipe joint database and an exhaust treatment device database, respectively, for each item number, and conditions required for pneumatic devices constituting a system are calculated. Then, pneumatic devices conforming to the calculated conditions are selected from the respective databases. At the first step, a pneumatic actuator satisfying a load condition, a strength condition and a speed condition is selected from the pneumatic actuator database on the basis of a calculation according to a basic equation.

  • Patent number: 3948083
    Abstract: A fluid pressure comparison apparatus including a pressure responsive member displaceable by the difference between two pressure sources being compared to vent fluid from one of the sources, when its pressure is greater than the other, through a port whose aperture is varied by the displacement of the pressure responsive member. The flow of vented fluid is measured in one of many possible ways to determine the excess pressure. The measurement may be displayed on an indicator or applied to control associated equipment. Various arrangements embodying the apparatus may be used for flow indication, flow control, leakage detection and indication and as warning or control equipment. The pressure responsive member is shown as a nylon reinforced rubber diaphragm but the nature of the member will depend on the absolute as well as the relative values of the pressures compared.
